HYDROCA RBONf-L'BUR N E R SPECIFICATION forming part of Letters' Patent No'. 768,367, datedAugust 23, 15504,

Application filed December 22, 1902. Serial No. 136,128. (No model.)

To all whom, it may concern/:

Be it known that we, ANDREW M. HUNT and THOMAS MIRK, citizens of the United States,

said body.

To comprehend the invention, reference `should be had to the accompanying sheet of drawings, wherein- Figure 1 1s a front view of the burner. Fig. 2 1s a longitudinal sectional view on line a, ce of Fig. 1.- Fig. 3 is a vertical sectional' end viewvo'n line of Fig. 4. Fig. 4 isa side view in elevation of the burner, and Fig.

5 is a longitudinal sectional View taken on line old ofFig. 1. f

The numeral l is used to indicate any suitable style of frame for the burner, which, preferably, is constructed of fire-clay brick, although any suitable material may .be employed for this purpose. Within the frame is arranged-a heating-body 2, consisting of pieces of refractory material. This bed or body surrounds or envelops an inlet-flue 3 for the hydrocarbon, which iiue is provided in its top and side walls with outlet-openings 4. This iiue shall hereinafter be termed a mixing or vaporizing flue.

At the entrance of the flue 3 is arranged a nozzle 5, which is attached to the free end of the supply-pipe 6 for the hydrocarbon. To regulate the discharge of the hydrocarbon into the iue 3, the nozzle 5 is provided with a controlling-valve 7 As the hydrocarbon is discharged into the vaporizingflue 3 during operation of the burner the suction caused thereby will, it is believed, draw intothe flue a sufficient quantity of air to create proper combustion. However, should such admission of air prove insufficient for the production of proper combustion, then additional air may be supplied through the air-flues 8 9.' These flues are arranged below the division-Wall l0, the air admitted thereto escaping through outlet-openings 11. By means of a slide 12 the supply of air through the flues 8 9 may be readily controlled. The air admitted by the said flues 8' 9y escapes into and circulates throughout the body 2 of refractory material.'

In starting the burner an initial heat is ob-r flame circulates throughout the body 2 the refractory material isheated to a red heat, thus producing, so tospeak, a bed of coals.7 Whether or not the flame projects above the body of refractory material is dependent upon the quantity of hydrocarbon admitted into the mixing or vaporizing flue, which is regulated by thel controlling-valve 7.

' From the foregoing it will be observed that the hydrocarbon properly vaporized is admitted to the interior of a body of refractory material, which when the hydrocarbon is ignited forms a heating bed or body for the burner.

While the invention is described for use in connection with furnaces generally, its use is not thus confined, inasmuch as the same principle may be successfully utilized for the construction of burners for various purposes. Neither do we wish to be understood as confining ourselves to any particular vconstruction or shape of the burner, as the essential feature is the introducing of the hydrocarbon into a broken or loose mass or body of refractory material.

Having thus described the invention, what is claimed as new, and desired to be protected by Letters Patent, is-

1. A hydrocarbon burner, comprising a frame, a vaporizing-flue therein, having top IOO and side sections, the side sections having a plurality of vertically-arranged slits, and the top being apertured intermediate the slits of the side sections, a body of broken refractory material inelosing the top and sides of said flue, and means for feeding the hydrocarbon into the Hue.

2. A hydrocarbon-burner, Comprising a frame, a partition-Wall extending the entire length and Width thereof and having a series of openings at its respective sides, longitudinally-extending air-flues below the partition, communicating with said openings, a longitudinally-extending vaporizing-iiue upon the partition intermediate said openings, and hav- 1 5 ing a series of apertures therein, and a body of refractory material within the i'raine eovering the top and sides of said ilue and the partition-Wall.

In Witness whereof We have hereunto set our 2O hands.
